no you describe narcissistic personality disorder.
Homo economicus would try get as much as possible for himself, or have others bear the cost (e.g. have society pay for roads but don't want to pay taxes).
They would not lower the quality of service for someone else out of spite without any gain for themselves, let alone waste time on it. They would also understand this would rise the cost of the service they might potentially want to use in the future.
Only narcissists would feel the desire to fuck up a service out of spite and ruin it for anyone else, just because they feel bad for not agreeing to the deal of having to pay
